STOVE.

SPECIFICATION forming part of Letters Patent No. 609,698, dated August 23, 1898. Application filed December 15, 1897. Serial No. 661,990. (No model.)

To all whom t may concern:

Beit known that I, ANTON OHNEMUS, a citizen of the United States, residing at Quincy, in the county of Adams and State of Illinois, have invented a certain new and useful Improvement in Stoves, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to certain improvements in heating-stoves, the principal objects of my invention being twofold-first, to provide for a thorough heating of the draft-air before it enters the combustion-chamber of the stove, which aids greatly inthe comsumption of smoke, and, second, to protect the outer walls of the stove-casing from the action of the severe heat of the stove at and near the place of combustion and around the fire box or basket.

With these Aobjects in view my invention consists in features of novelty hereinafter fully described and claimed.

Figure lis a side elevation of a stove, partly yin section, showing my improvements thereon. Fig. II is a plan view of the fire-pot. Fig. III is an axial section from the front to the back of the body portion of the stove. Fig. IV is an axial section 'from side to side of the body portion of the stove, looking toward the back of the stove. y

Referring to the drawings, l represents the base of the stove, 2 the outer shell or casing, and 3 the top', all of which may be made of any common form or shape. 4 represents the fire pot or basket supported within the casing in the usual manner and which is provided with a segmental outwardly-extending flange 5 at the top,which snugly fits the interior of the casing, except at the back of the stove, where it is cut away from A to B, forming an airpassage 6, as shown in Fig. II. This flange 5 is formed in cup shape, as shown in Figs. I and III, and it receives the lower end of a shield 7, which seats partly on the body of the fire pot or basket and partly on the flange thereof. The shield flares upwardly, being larger at the upper end than at the lower end, and at the top it snugly fits the interior of the casing of the stove, as shown in Figs. I and III, where it is represented as having a ii-ange 8,thatbears against the casing. This form of the shield provides an air-chamber 9 between the shield and the casing, and the fire pot or basket is also so formed as to provide an air-chamber 10 between it and the casing. The lower end of the basket is slotted,as shownat 11, for the admission of air beneath the fuel in the basket.

The lower end of the shield 7 is cut away, forming an airpassage l2 between the shield and the basket. This passage extends entirely around the shield, except 'at the back of the stove, where the passage 6 is made in the flange of the basket, and at this point the shield rests down upon the flange of the basket, as shown, so that "air passing from the chamber l0 into the chamber 9 through the passage 6 cannot pass directly into the combustion-chamber within the shield, but is compelled to circulate in the chamber 9 and then passes, as shown by the arrows in Fig. I, through the opening l2 to the interior of the shield.

By causing the air to circulate in the chamber 9 it becomes highly heated and enters the combustion-chamber or the interior of the shield at a high temperature, thus materially aiding in the consumption of the smoke and products of combustion.

Another advantage arising from the circulation of air in the chamber 9 is that the outer casing is protected from the intense heat of the combustion-chamber of the stove immediately above the fire-pot or basket, where the casing would otherwise be subjected to the most severe heat of the stove.

To support the shield on the basket at the cut-away portion 12, I provide the shield with lugs or ears 13, that rest upon the flange or npper end ofthe basket, these lugs or ears acting to a certain extent also as air-deflectors,`

causing counter-currents or eddies of the air in the chamber 9 beforeiit passes into the combustion-chamber, whereby the air is detained in its passage and longer subjected to heat before entering the combustion-chamber.

While I have described my invention and have shown it as applied to a stove, yet it is evident that my invention might be applied to hot-air furnaces or other heaters.

I claim as my invention-- A stove comprising a nre-pot formed at top witha flange having a segmental air-passage at the back portion of the stove,'and a shield portion of the stove seating on the body of the formed at the top with a ange, at bottom With re-pot g substantially as described. a segmental air-passage extending around the front and sides of thestove, and at the front 5 and sides of the stove with radial lugs whereby In presence ofv the shield is supported on the ange of the JOHN V. FISHER, rire-pot; the portion of the shield at the back GEO. SWEETRING.
